Insure good ground from power supply to workpiece. Poor ground may cause
damage to any or all components. Use only with compressed air. See manual.
Smoke, fumes, and gases can be dangerous to your health. Use adequate
ventilation. Keep your head out of the smoke.
Protect yourself and others. Wear ear, eye, and body protection.
Noise can damage hearing.
Electric shock can cause injury or death. Disconnect power before servicing.
Arc rays, hot slag, and sparks can injure eyes and burn skin.
Welding sparks can cause res and explosions.
Assurez la bonne terre de l'alimentation d'énergie à l'objet. La terre pauvre peut endommager
quelques des ou tous composants. Employez seulement avec l'air comprimé. Voir le manuel.
La fumée, les émanations et les gaz peuvent être dangereux pour votre santé.
Employez à ventilation proportionnée. Gardez votre tête hors de la fumée.
Protégez-vous et d'autres. Portez l'oreille, l'oeil, et la protection de corps.
Le bruit peut endommager l’ouïe.
Un choc électrique peut causer des blessures ou la mort. Déconnectez la puissance
avant l'entretien.

1 Travel System Power Connector
Two (2) 4 amp AC power receptacles provide AC power for a travel system if needed, 110 VAC or 220 VAC. The
Remote Pendant controls when these receptacles receive AC power through the Remote Pendant travel delay circuitry.
Only the AC power voltage (110V or 220V from the Input Power AC) that the Control Box is connected to will be delivered.
2 Air Out Connector Delivers compressed shop air to the Torch Head when the
START
“Start” button is pressed on the Remote Pendant.
3
Connector to Torch Head Electrode
Motor
Delivers the signal from the Control Box to the Torch Head to either feed or retract the electrode to maintain the
preset arc voltage.
4 Remote Pendant Connector
Links the Remote Pendant to the Control Box to initiate start/stop of the gouging operation.
5 Circuit Breaker w/reset
Circuit breaker reset push button for 110 VAC and 220 VAC AC Travel System Power Connector receptacles.
6 ON/OFF switch Control Box ON/OFF control switch with built in 5 amp circuit breaker and reset.
7 Input and Output DC Power Conn. Output and Input DC (+) positive power buss connections.
8 Air In Connector This port accepts compressed shop air to the Control Box.
9 Power Supply Connector
Links the Control Box to the Power Supply. On demand from the Remote Pendant the internal contactor of the Power
Supply can be closed and opened to deliver the current to the Torch Head.
10 Input Power (AC) Delivers AC voltage to the Control Box from a standard wall receptacle.
11 Signal Wire Connector
Allows the Control Box to detect open circuit voltage when the Power Supply contactor is closed.
12 Control Box Hold Down Fixture Hold down fi xtures located on both sides of the Control Box to allow fastening to a base.
13 Remote Pendant Cradle Secure holding fi xture for Remote Pendant.

1 Motor
This motor feeds the electrode away from and towards the work. The Motor’s action is con-
trolled by the Pendant settings.
2 Motor Cable
This Motor Cable end is connected to the Control Box via a cable assembly that comes in 3, 15,
25, or 50 foot lengths.
3 DC Power Cable Busbar This is the connection point on the Torch Head for the DC power cables from the Control Box.
4 Air Inlet Air is fed into a 3/8” NPT fi tting on the Torch Head using an air supply line from the Control Box.
5 Air Plenum
This housing circulates air around electrode housing before releasing in a directed spray to
remove gouging slag.
6 Electrode Release Lever
This lever is used to open the Motor Feed assembly allowing the operator to manually remove
or replace an Electrode.
7 Electrode Size The guide inside helps the insertion of the electrode through the Torch Head.
8 Carriage Mounting Fixture
The mounting bracket that comes with the Torch Head allows it to fasten to a vertical adjustment
assembly which is either mounted on a travel system or stationary fi xture.
9 Air Plenum Shield This metal shield protects the Air Plenum housing from slag splash back.
10 Torch Head Shield This metal shield protects the motor and housing from slag splash back.
